I I HHH H r/WM l l/ All? United? States Patent 2,888,721 WINDOW AndrewT. Hagerty, Elkhart, Ind., assignor to The \dlake Company, Elkhart,Ind., a corporation of Illinois Application July 20, 1956, Serial No.599,119 Claims. (Cl. 20-69) This invention has to do with windows of thetype in which a sash is pivotally mounted in a frame and sealed in itsclosed position by a continuous sealing gasket located between the outerperiphery of the sash and the inner periphery of the frame.

It is a general object of the invention to provide in a window of thetype described new and improved sealing or gasketing means between thesash and the frame in the form of a continuous strip member having abase section adapted to be frictionally retained in a peripheral recessin the sash and a compressible or distortable tubular section which isadapted to project across the clearance space between the sash and theframe.

It is a more specific object of the invention to provide in a window ofthe type described a new and improved sealing gasket comprising a metalbase or holder strip which is bent upon itself and which clamps betweenthe flange forming legs thereof the marginal edges of a reversely foldedstrip of fabric covered rubber sheeting, with the latter projectingtherefrom in the form of a tube and being adapted to span the spacebetween the sash and the frame and resiliently engage with the inward 1yfacing surface of the frame thereby to provide a weather seal betweenthe sash and the frame.

It is another object of the invention to provide a sash and a sealinggasket of the character referred to wherein the sealing gasket ischaracterized by being divided into annular corner sections andconnecting strip sections which are individually insertable in the edgerecess provided in the sash and frictionally retained therein whereby tofacilitate initial assembly of the gasket and the sash and subsequentreplacement of the gasket when required.

These and other objects and advantages of the invention will be apparentfrom a consideration of the window construction which is shown by way ofillustration in the accompanying drawings wherein:

Figure 1 is a perspective view of a window constructed in accordancewith the invention, the sash being shown in open or angular relationrelative to the frame;

Figure 2 is a partial elevation, to an enlarged scale, of the lowerportion of the window with the sash in closed position relative to theframe;

Figure 3 is a section taken through the connecting pivot between thesash and the frame on the line indicated at 33 in Figure 2, to anenlarged scale;

Figure 4 is a fragmentary view, on a still larger scale and withportions broken away, showing the details of a corner of the sash andthe associated sealing gasket;

Figure 5 is an exploded view, on an enlarged scale, showing in elevationa corner portion of the sash with portions of the sealing gasket inposition for insertion in the edge recess in the sash;

Figure 6 is a section, on a larger scale, taken on the line 6-6 ofFigure 5; and

Figure 7 is a perspective view, on an enlarged scale, of a portion ofthe sealing gasket.

Referring to the drawings, the window includes an 'ice outer stationaryframe 10 of generally rectangular form, which frame is adapted to beanchored and sealed any suitable manner in an opening in the wall of thebuilding. The frame 10 surrounds and fits closely about a glazed sash 11of the same general rectangular form. The rail members 12 of the frame10 and the rail mem bers 13 of the sash 11 are both preferablyconstructed of extruded aluminum but either or both may be cori--structed of any other suitable material. I

The sash 11 is pivotally connected, preferably midway between its sides,to the frame 10, the pivotal connection being effected by aligned topand bottom pivot pins 14 and 15. The sash 11 is provided about its outerperiphery with a pair of laterally spaced, continuous, outwardly openinggroove or recess formations 16, preferably of generally rectangularcross section, in which a continuous sealing member 17 is partiallyhoused. The continuous recesses of slots 16 open outwardly of the edgeface 18 of the sash rails 13 and are in confronting relation with theinwardly facing periphery 19 of the frame 10. The recesses 16 are spacedlaterally so that they are 10- cated near the outer edges or faces ofthe sash rails 13 on opposite sides of the supporting pins 14 and 15which are located in the center or intermediate the side edges of thesame.

The pins 14 and 15 are mounted in a similar manner being secured in asleeve 20 (Figure 3) in the bottom sash rail 13 and projecting into thebearing sleeve 21 in the bottom rail 12 of the frame 10. The sleeves 20and 21 have confronting flange or shoulder formations 22 and 23 whichproject slightly from the faces of their respective rails and hold thesash 10 in spaced relation within the frame 11.

The Weatherstrip or sealing member 17 is of special construction and isarranged to provide a continuous seal extending between the confrontingfaces 18 and 19 of the sash 11 and the frame 10. The sealing member 17comprises a holder member or base section 24 and a resilientcompressible tubular member or section 25 projecting therefrom. Thetubular section 25 is preferably formed from a napped cloth sheetingvulcanized to a relatively thin base sheet of rubber. The holder member24 is preferably formed initially from a relatively narrow fiat strip ofrelatively thin metal such as aluminum sheeting or the like. Infabricating the sealing member 17, a relatively narrow metal strip isfolded on its longitudinal axis to provide a channel of generally U-shaped cross section while a strip of napped rubber sheeting is foldedon its longitudinal axis to form the tubular section 25 adjacent oralong the fold and marginal portions or flanges 26 which are broughttogether into flatwise relation and engaged between the legs 27 of thefolded aluminum strip member or holder 24 as shown in Figure 7. The legportions of the strip member 24 are creased somewhat at 28 adjacent thefold area which results in a slight outward bowing or bulging of themarginal portions permitting these portions to be resiliently compressedwhen the member is inserted in the recess 16 so that the member isresiliently held in position in the recess. The tube forming portion orsection projects from the holder 24 so that when the weatherstrip member17 is attached to the rails 13 of the sash 11 by seating the holdermember 24 in the recess 16, the tubular section 25 projects into thespace between the confronting faces 18 and 19 of the sash 11 and frame10 providing an allweather seal between the same and bridging the spaceseparating the two members.

In preparing the sealing member 17 for assembly in the grooves orrecesses 16 in the sash rails 13 corner pieces or members 29 areprovided as shown in Figure 5, which are formed by abutting the miteredends of two relatively short sections 30 of the assembled sealing stripmaterial as at 31 and vulcanizing the abutting edges of the gasketforming tubular section 25, as indicated at 32. The other ends of thesections 30 are cut on transverse lines except for the ends of thetubular section 25 which are cut on a diagonal 'line, as shown at 33,providing an end portion adapted to be tucked into the correspondingtubular section 'of an adjoining straight length 34 of the sealingmember 17 which extends in the recess 16 between the corner members 29.With this arrangement, the assembly of the sealing member 17 with thesash frame to provide an unbroken or continuous seal is readilyaccomplished even after the sash 11 is installed in the frame 10. Theleg portions 27 of the weatherseal holder member 24 have sufficientresiliency to normally hold the strip members in resilient engagementwithin the groove 16 so that the tubular section 25 thereof'projectsbetween the confronting faces 18 and 19 is distorted or compressedsomewhat when the sash 11 is in the closed condition as illustrated inFigure 3.

While specific details of construction and specific materials have beenreferred to in describing the illustrated form of the invention, it willbe understood that other details of construction and other materials maybe resorted to within the spirit of the invention.
